Editing Rheged (section)

==Southern Rheged==
A second royal genealogy exists for a line, perhaps of kings, descended from Cynfarch Oer's brother: Elidir Lydanwyn. According to ''[[Bonedd Gwŷr y Gogledd]]'' Elidir's son, [[Llywarch Hen]], was a ruler in North Britain in the 6th century.{{sfn|Chadwick|1959|p=121}} He was driven from his territory by princely in-fighting after Urien's death and was perhaps in old age associated with [[Kingdom of Powys|Powys]]. However, it is possible, because of internal inconsistencies, that the poetry connected to [[Powys]] was associated with Llywarch's name at a later, probably 9th century, date.{{sfn|Chadwick|1973|pp=88–89}} Llywarch is referred to in some poems as king of South Rheged, and in others as king of Argoed, suggesting that the two regions were the same. Searching for Llywarch's kingdom has led some historians to propose that Rheged may have been divided between sons, resulting in northern and southern successor states. The connections of the family of Llywarch and Urien with Powys has suggested to some, on grounds of proximity, that the area of modern [[Lancashire]] may have been their original home.{{sfn|Chadwick|Chadwick|1940|p=165}}
